ADJUSTER FOR WELL-PUMPING- AFPARATUS.,

Application filed May 13,

Be it known that I, FRANK I. NnvILIi,'of Houston, county of Harris, and State of Texas, have invented an Improvement in Adjusters'for fell-Pumping Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This in"vention aims to improve pump adjusters to adapt them for use with hollow polished rods to which an expansible fluid is supplied to aid in pumping.

Further aims are to provide suitable apparatus for operating deep `well pumps which shall be strong, simple in construction, and easily and quickly adjusted to working conditions.

Other aims and advantages of my invention will appear in the body of this specification in connection with the description of the illustrative embodiment shown in the accompanying drawings, wherein:

vFigure 1 is a side elevation of part of a deep well pumping apparatus showing parts in section and other partsbroken;

Fig. 2 is an enlarged fragmentary end elevation of a portion of Flig. 1 showing the adjuster partly in section, other parts being broken away;

Fig. 3 is an enlarged perspective View of 4a spacer member; and

Fig. 4 is an enlarged perspective view o another form of spacer members.

va5 i Referringto Fig. 1 of the drawings, wherein the invention is shown applied to -an oil well pumping rig of common type, preferably I provide an outer well casing 1 havi ing a. casing head 2 of usual construction tion pipe 6.

and a well tube 3 is concentrically arranged in the casing and preferably extends to near the bottom of the well. The well tube 3 has a slightly reduced working barrel 4 at its lowerend which isclosed by a standing valve 5 and provided with a perforated suer A piston or working valve 7 is arranged to-reciprocate in the working barrel 4 and is operated by a iuid conducting tubular sucker or piston rod 8 having perforations l 9 preferably communicating with the working barrel or well tubing above the working valve. The sucker rod extends upwardly through the usual stuffing box '10 arranged on the upper end of the well tubing above the tee 11 to which the usual discharge out- 192e". senin No. 560,551.

through and reciprocates in the stu ng box, j isf'adjustably secured by means of an'ad- G0 juster pipe 14 'or other suitable connection, which is preferably threaded to an adjuster l5 (see Fig. 2). The -adjuster is pivotally mounted on the walking beam 16 of a stand. ard pumping rig in the embodiment shown; but itis to be understoodA that the adjuster may be' employed in other types of rigs.

The adjuster 15 preferably comprises a four way eXtra heavy tubular member having branches 17, 18, 19 and 20 (Fig. 2), 70 opposite pairs of which are adaptedto form trunnions by journaling them in appropriate bearings in the end of the walking beam. They may be held against displacement by an adjuster board 21 suitably secured to the Walkingbeam. The upper vertical branch 20 of the adjuster is internally threaded tol receive a plug 22 which has a hook.receiving ring 23 on its upper end for lifting purposes. All of the branches of `my improved four way adjuster are preferably the same size and length and are provided with both internal and external threads so the adjuster may b reversedin position if necessary.

The adjustable connection between the tubular polished rod 13 and the adjuster pipe 14, or other means for connecting itto the adjuster, preferably comprises an in-v verted stuffing box 23 through which the polished rod passes, and which is detachably connected to the adjuster pipe'l4 by means of a threaded sleeve 24. The upper end of the polished rod 13 mayhave a shoulder or annular collar 25 (Fig. 2) preferably detachably andadjustably secured thereto as 9d by screw threads. The collar 25 is adapted to telescope ivithin the adjuster pipe 14. A. removable spacer, such as a section of pipe 26, or a plurality of spacers or pipes of ap propriete length, is adapted to rest upon the top of the stuiing boX and maintain the shoulder or collar 25 at the proper elevation.

In practice a series of short sections of pipe 26 ot' diiferent lengths are provided in` order that an appropriate one may be in'- serted between the collar 25 and stuffing box 23 to properly 'space the working valve 7 from the standing valve 5 when necessary. (See the dotted position of the polished rod in Fig. 2.)

instead of employing sections of pipe. as shown in Fig. 2 a series of semi-cylindrical spacer members 27` (Fig. 3) or la series of U shaped spacers 28 (Fig. i) may be in 28 in Fig. 2. '.In case either of these types of spacers are used it is not necessary tol remove the-collar 25 onthe'polished rod 13 .in order to make any desired adjust-ment in the elevation of the sucker rod.' It will be noted that one or more of the U shaped spacers may be inserted above and between the upper end ofva pipe section 26 or the semi-cylindrical sections 27 and the collar 25 to effect the necessary adjustment of the working valve 7.

If only a 'small adjustment is necessary, the collar 25 may be screwed up or down the desired distance onthe polished rod thus effecting a very simple and accurate adjustment. The fluid connection to the adjuster '15 preferably comprises a swinging joint 29 having a nipple 30 threaded into one branch 17 thereof (Fig. v2) and a pipe section 3l is connected to the swivel joint 29 and extends along the walking beam 16 terminating in another swin ing or swivel joint 32 which is held in axlal alinement with the saddle pin 33 of the Walking beam, so that the pipe section 31 may oscillate with the walking beam. A gas or air pipe line '34,

leading from a suitable source of gas under pressure, is connected to the swivel 32.

The branch 19 of the adjuster is closed by a plug 35 so that gas under pressure entering the adjuster passes downwardly through the upper end of the polished rod and through the sucker rod into the wel/l as hereinbeforc described. Thus gas is discharged continuously into the discharge column from the pump .to aid -in'liftiug the liquid to the surface.

An advantage of the construction illustrated is that it' the threads in the lower branch of the adjuster should be sheared y due to the enormous tension thereon (which when operating in a 3000 foot well, for example, exceeds 14000 pounds) or in case the internal threads in any one of the branches should be sheared out or stripped, the connection may be made by means of the external threads by using an ordinary sleeve coupling reducer (not shown).

It will be observed that any one of the branches of the adjuster is adapted to receive the adjuster pipe 14, and likewise the two vertical branches 18 and 20 ma 'be used as trunnion members instead o the lbranchesJ 17 and 19. Thus the interchange.

. ability of the branches renders the device capable of withstanding long wear and the tremendous strains to which it is subjected.

In operating the apparatus the necessary 10 in thejusual manner when the walking,

beam is in its. lowest position. Then'the olished rod 13 may bel st'ufiing box 23 may be removed from the 'i sleeve 2l and the walking beam moved upf.

wardly away from the top end of the olished rod, until the adjuster' pipe is liftedl above the end of' the polished rod.V Then the collar 25 may be screwed further downv on the polishedi-od or, it necessary, a'pipe sectionof different length may be readily substituted for the 'section 26 by removing the annular collar 25 and insertingv a new section. Also the effective length of the spacer member may be increased bysimply inserting one or more of the U shaped spacers 28 either above or below the-spacer section, thus avoiding the necessity for removing the collar 25and effecting afquick .ad- A justment. Another method of making an adjustment may be accomplished by removing the plug 22, clamping the polished rod 13 in its extreme upper position, then lowerl ing the walking beam to expose the upper end of the polishe'drod through the branch 20 of the adjuster and inserting the spacer members as hereinabove described. The walking beamis then raised and thev plug 22 reinserted. Thus the adjustment may be easily and quickly made.

Another important feature of my adjuster is that in case the height of the rig or walking beam is not sufiicient to afford a clear'- ance between the stufiing boxes 10 and 23 onl the down stroke, the adjuster pipe 14 may be removed from the branch 18 and inserted inv the upper branch 20 in which .case the stufling box 23 will be threaded directly into the lower branch 18.

Having thus fully desc-ribedmyinven tion and one form thereof selected for illusim trative purposes, it is to be understood that.

the invention is not restricted to the embodiments and means of operation shown but it 1s susceptlble of various modifications and changes involving omission of parts, alter ation, substitution, addition and, rearrange ment of parts.
